Configure SLOs in your k6 script to test the health of your services.
Create tests faster with our test builder, recorder or converters (JMeter, Postman, Swagger).

No XML. No DSL. Just familiar scripting with ES6 JS
"The engineering effort of writing tests for just one of our microservices was going to be 2+ Engineering weeks in JMeter, versus the ½ day it took us in k6!"

I’ve been trying a bunch of different tech lately for load testing and man nothing comes close to how good @k6_io is
@k6_io thank you for creating an amazing open source product. I wrote my own thread ripper for load testing and you just saved my socks with the integration tools you have by default. Anyone looking to do load testing highly recommend using k6. It also reminds me of snowboarding.
It's time for me to once again sing the praises of @k6_io. If you've ever written a load test I think you'll likely agree it is the grungiest of grungy tasks. k6 makes it fun. It's like Greasemonkey for load testing. Cannot recommend enough.
I've toyed with a few load testing tools over the years, but only today tried @k6_io, and wow, is it pleasant to use. Haven't tried the hosted version, but for quick and easy CLI stuff, absolutely wonderful.
I love products like @k6_io - very technical and geeky domain, yet the product is extremely user friendly and you can understand and start using it within *seconds*, not even minutes. Great job.
personally using @k6_io and its has helped us quite a lot already. Definitely worth adding to your testing pipeline.
Lately I have been using @k6_io for performance testing the RESTful APIs we build and I simply fell in love with it. It so simple and easy to use, i highly recommend it!!
For anyone interested in load / stress testing, I’ve been using @k6_io recently and has been an absolute pleasure. Script up your flow using JS and away you go. Load tests in source control FTW. API for build sever runs too, beautiful.
